Conditional rendering based on a boolean value in React JS

Question

I'm working with a JavaScript object and I'm trying to render a button based on a boolean value, but I'm running into an issue. Here's a snippet of my code:

const toy_material = toy.material.allow; // This is a boolean value that can be true, false, undefined, or null
console.log("toy_material", toy_material);

When I console.log("toy_material", toy_material), nothing is showing up in the console. I'm also trying to conditionally render a button based on the value of toy_material. I want the button to show regardless of whether toy_material is true, false, undefined, or null.

How can I achieve this? Any help would be greatly appreciated!

I tried logging the value using console.log("toy_material", toy_material); but nothing is printing in the console. I'm expecting it to log the value whether it's true, false, undefined, or null, so I can use that value to conditionally render a button. I want the button to render in all cases, regardless of what the boolean value is. How do I achieve this?

Your code snippet is not enough to determine what could be going wrong with your code. More information is needed to be able to help with your problem. — Hamed Jimoh

You should consider using optional chaining to check if the properties you are trying to access are being returned first; then, depending on the response, you can proceed. — Sofiyullahi Olamilekan Jamiu

first use ? operator with object properties which help manage null, undefiend
const toy_material = toy?.material?.allow;

in order to render the button if toy_material is true it shows button else in case of null, undefined, and false nothing will shown. here is how you can do it.

return (
  <div>
   { toy_material && <button>click here!</button> }
  </div>
)

I Hope it works for you.

They stated that they want the button to be shown regardless of the value of toy_material. This won't achieve that. Regardless, we're lacking info.
